It seems I don't have permission to report bugs, so I place it here.
When browsing my repository hosted inside Phorge, I see the following exception showing up:
```
Diff Parse Exception: Expected '\ No newline at end of file'.

My locale is Hungarian and at the end it says exactly "No newline at end of file" just in another language.
Reproducer:
```lang=bash
echo A > a.txt
echo -n A > b.txt
diff a.txt b.txt
```
```lang=diff
